linux2.6.38与2.6.28中wifi驱动问题.

经过一个星期的研究发现现样的操作在2.6.38中就能正常找到wlan0,但是对2.6.28而言就不行,2.6.28中在if_sdio.c中没有得到注册,没有进入probe中.是不是28的内核的wifi驱动或者是与wifi相关的驱动不完善还是什么?

是的，所以才需要升级到36，我们并非一味求最新，要有意义才行。

哪28的有没有什么办法,能让他找到wlan0呢?需要改哪个驱动或者改哪些地方?

以下是我修改后的内核部分信息:

无法识别mmc1

用38不是挺好的，28太老了，将来升级都麻烦，现在麻烦也不少了

现在在研究内核驱动,不是能不能用的问题,是会不会的问题.只是想把这个研究清楚,只希望高手指点指点

你看下sdio wifi通道的时钟问题,打开debug,2.6.28是可以支持sdio wifi的,我以前做过.

能不能说的具体点,或者你把你改好了的内核源码发给我,我自己研究也可以,谢谢.

现在应该是sdio的驱动应该没有问题我觉得,主要是wifi无法注册.

38和36的都没有问题,只要把相关选项选上加上固件就可以了,可以28的就是不行,想弄个明白.
